WRECKING TOOL.

Application filed September 22, 1926. Serial No. 136,998.

This invention relates to a wrecking bar or tool of the characterdesigned for use in salvaging lumber, dismantling framework and thelike.

It is aimed to provide a novel construction possessing the details andadvantages which will be specifically pointed out or appear in thedescription following taken in connection with accompanying drawingsillustrating an operative embodiment.

In said drawings Figure 1 is a view in perspective illustratingthe toolas in use;

gigure 2 is a perspective view of the tool, an

Figure 3 is a perspective view of the tool with the parts thereofdisassembled to disclose details.

In carrying out the invention, an operating pry or lever is shown at 10having an integral cam portion as at 11 in which a disk 12 is looselydisposed for rotation. Said disk 12 has an eccentric hole 13, thereinthrough whichv a rivet or bolt 14:, loosely passes, which bolt connectslinks 15 disposed at opposite sides of the lever 10. The forward ends ofsaid links 15 are disposed in advance of the cam 11 and enter notches 16of a shoe 17, in the form of a plate, and to which shoe such ends arepivotally connected as by a pin or bolt as at 18.

At the forward end of the lever 10, it has a transverse cross head orabutment bar at 19, formed on a'diagonal extension 20 of the cam 11.Said bar 19 extends laterally beyond the plane of the correspondingsides of the shoe 20 for the purpose hereinafter stated.

In operation, the device may be used in house wrecking, dismantlingframeworks or the like and for instance to remove clapboarding as at 21from scantling as at 22. The lever is manipulated so that the cross heador bar 19 will engage against the scantling 22 on the edge to which theclapboard 21 is secured and the shoe 17 against the abutting face of theclapboard 21. WVith the parts in the positions stated the lever isrocked so that the cam action of the parts will serve to pry theclapboarding 21 loose from the scantling 22. It will be understood thatby using this tool for dismantling buildings the timbers will not besplit or defaced but will be saved for reuse, and further that thedevice will save time in wrecking buildings.

Changes may be resorted to provided they fall within the spirit andscope of the invention. v

I claim as my invention 1. A tool of the class described comprising alever adapted for abutment against a part of the work, a shoe adaptedfor abutment against another part of the work, a disk journaled on thelever, means connecting the shoe to the disk eccentrically of thelatter.

2. A tool of the class described comprising a lever adapted for abutmentagainst a part of the work, a shoe adapted for abutment against anotherpart of the work, a disk journaled on the lever, means connecting theshoe to the disk eccentrically of the latter comprising an arm pivotallyconnected to the shoe.

3. A tool of the class described comprising a lever having a camportion, a disk journaled in said portion, links at opposite sides ofthe disk pivotally connected thereto and eccentrically thereof, a shoepivotally connected to the links, and a bar at the forward end of thelever disposed transversely thereof for engagement with the work inopposition to the shoe.

In testimony whereof I aflix my signature.

JOHN E. HOFFMAN.
